crossover help

[eastonc]

Hello everybody. first off i am new to the forum. I have been doing car audio for years now and am getting into home audio now. I was given a pair of CSS SDX7's and did a search on them and it appears as if they are a replacement for the adire audio estremon 6.8's. I came accross the humble homemade hifi site and they have a build in there with the adire drivers and a pair of seas tweeters. before I purchase the tweeters I was trying to find out where to buy the crossover parts, but I cant find an inductor with these specs 1,80 mH 12 gauge wire with a resitance of 0.25 ohms. does anybody know where I may be able to find one or if this would be a good match of speakers. if so some help with the crossover would be excelent. Thanks a bunch

Hi, just find 1.80mH inductors with a resistance of less than 0.25 ohms, /Sreten.

They aren't cheap, but Michael Percy Audio has them...

SOLO & ALPHA-CORE COPPER FOIL AIR CORE INDUCTORS
*Unique 5% tolerance 16ga, 14ga & 12ga inductors wound from an ultra-thin .003" 4N copper foil with polyester & polypropylene insulating
materials and a varnish dip coating, made in the USA by Solo (Solo out of business, phasing out) & Alpha-Core.
*Low DC & AC resistance, very low power loss, minimal phase shift and skin effect resistance to 100kHz, no hysteresis distortion, the
most transparent inductor made today, rapidly becoming the inductor of choice in high end speaker systems.
*All values listed below are stock, sorry due to manufacturer's new high minimum line item requirements, custom values no longer available.
*16ga are 1.0" High (no more 16ga after our stock is gone), 14ga are 1.25-1.42" High, 12ga are 2.0" High, diameter approx. as listed.

1.80mH.......12ga......... .250Ω ..............3.65" .........54.50

So if you really want the exact match they are available, but as Sreten said you could always get something with even lower DCR, though 0.25 Ohms is already pretty low for a coil that size, and something lower will probably be even more expensive!!
